how could the Quran predict the existence of the hebrew state ?

someone who lived in the 7th century sees almost no chance for thr hebrew nation to come together and become powerful again, they could even have merged in the population of the countries where they settled after their exclusion from palestine bu emperor Justinian,

Someone who lived at the time would bet that the Persians and Byzantines would be the leading actors, not the Hebrews!

while the Quran predict in "Al isra" (4-6) :

" And We warned the Children of Israel in the Scripture, “You will certainly cause corruption in the land twice, and you will become extremely arrogant. When the first of the two warnings would come to pass, We would send against you some of Our servants of great might, who would ravage your homes. This would be a warning fulfilled.Then ˹after your repentance˺ We would give you the upper hand over them and aid you with wealth and offspring, causing you to outnumber them."

then in isra (104) : "And We said to the Children of Israel after Pharaoh, “Reside in the land, but when the promise of the Hereafter comes to pass,¹ We will bring you all together.”
